At the end of the day, Helen throws all the change from her purse into a box. The box contains only pennies, nickels, and dimes. At the end of one week she found that the total value of the coins was $3.7. If the number of dimes was 9 more than the number of nickels and the number of pennies was 8 more than the number of nickels, how many nickels were in the box?

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
